Chondroitin sulfate as good as widely used anti-inflammatory for knee osteoarthritis

EurekAlert! - Lun, 05/22/2017 - 22:00
High quality (pharmaceutical grade) chondroitin sulfate is as good as a widely prescribed non-steroidal anti-inflammatory drug (celecoxib) for the treatment of painful knee osteoarthritis, concludes research published online in the Annals of the Rheumatic Diseases.

Fiber-rich diet linked to lowered risk of painful knee osteoarthritis

EurekAlert! - Lun, 05/22/2017 - 22:00
A fiber-rich diet is linked to a lowered risk of painful knee osteoarthritis, finds the first study of its kind, published online in the Annals of the Rheumatic Diseases.

Microhabitats enhance butterfly diversity in nature's imitation game

EurekAlert! - Lun, 05/22/2017 - 22:00
The spectacular range of colors and patterns that butterflies use to deter predators appears to result in part from very specific environmental conditions in so-called 'microhabitats,' researchers have found. This study helps to answer a paradoxical question in science; since species mimic each other's characteristics to ward off predators, theoretically they should all eventually develop the same pattern. Instead, there is a remarkable diversity of patterns which achieve this common goal.

Regular chocolate consumption may be linked to lower risk of heart flutter

EurekAlert! - Lun, 05/22/2017 - 22:00
Regular chocolate consumption may be linked to a lower risk of developing the heart rhythm irregularity atrial fibrillation, also known as heart flutter, finds research published online in the journal Heart.

Vitamin D supplements could help pain management

EurekAlert! - Lun, 05/22/2017 - 22:00
Vitamin D supplementation combined with good sleeping habits may help manage pain-related diseases. This paper published in the Journal of Endocrinology, reviews published research on the relationship between vitamin D levels, sleep and pain management, and reports that levels of vitamin D combined with good quality sleep could help manage conditions including arthritis, menstrual cramps and chronic back pain.

Friends help female vampire bats cope with loss

EurekAlert! - Lun, 05/22/2017 - 22:00
When a female vampire bat loses a close relative, she may starve, because she depends on her mother and daughters to share blood by regurgitation. Vampires who have more non-kin social bonds (friends), do better when this happens.

Eating chocolate may decrease risk of irregular heartbeat

EurekAlert! - Lun, 05/22/2017 - 22:00
Consuming moderate amounts of chocolate was associated with significantly lower risk of being diagnosed with atrial fibrillation (AF)--a common and dangerous type of irregular heartbeat--in a large study of men and women in Denmark led by researchers at Harvard T.H. Chan School of Public Health and in Denmark.

Enforcing a weekday bedtime could help your child get sufficient sleep

EurekAlert! - Lun, 05/22/2017 - 22:00
Enforcing rules about bedtimes could help your child get the sleep they need on weekdays, according to new research published in the open access journal BMC Public Health.

ACR opposes sweeping healthcare cuts in Trump administration budget

EurekAlert! - Lun, 05/22/2017 - 22:00
The American College of Rheumatology expressed opposition to the Trump Administration's proposed budget cuts to federal programs and institutions that provide critical resources in the fight against rheumatic diseases, including the National Institutes of Health (NIH), the US Food and Drug Administration (FDA), and the Children's Health Insurance Program (CHIP). The rheumatology provider community praised budget proposals to repeal the Independent Payment Advisory Board (IPAB) and to increase funding for Graduate Medical Education (GME) programs.

Lizards may be overwhelmed by fire ants and social stress combined

EurekAlert! - Lun, 05/22/2017 - 22:00
Lizards living in fire-ant-invaded areas are stressed. However, a team of biologists found that the lizards did not exhibit this stress as expected after extended fire ant exposure in socially stressful environments, leading to questions about stress overload.

Stingless bees have specialized guards to defend their colonies, study reveals

EurekAlert! - Lun, 05/22/2017 - 22:00
Several species of stingless bees have specialized guards or soldiers to defend their colonies from attacks by natural enemies. The differentiation of these guardian bees evolved in the last 25 million years and coincided with the appearance of parasitic 'robber' bees, which represent a major threat to many stingless bee species. These discoveries were made by a group of researchers in Brazil in collaboration with colleagues in Germany.

How to prevent 3-D printing hacks? Install secret flaws and share the decoder ring

EurekAlert! - Lun, 05/22/2017 - 22:00
Since the global supply chain for additive manufacturing (AM)-- also called 3-D printing-- requires companies to share CAD files within the organization or with outside parties via email or cloud, intellectual-property thieves and malefactors have many opportunities to filch a manufacturer's design files to produce counterfeit parts. Researchers have discovered ways for manufacturers to turn the tables on thieves by deliberately embedding hidden flaws in CAD files to thwart intellectual property theft.

Blood test offers improved breast cancer detection tool to reduce use of breast biopsy

EurekAlert! - Lun, 05/22/2017 - 22:00
A Clinical Breast Cancer study demonstrates Videssa Breast can inform better next steps after abnormal mammogram results and potentially reduce biopsies up to 67 percent.

South highest, Northeast lowest for child auto fatalities

EurekAlert! - Lun, 05/22/2017 - 22:00
The number of motor vehicle fatalities involving children under age 15 varies widely by state, but occurrences are more common in the South, and are most often associated with improperly or unused restraints and crashes on rural roads, a new review of child-related auto fatalities shows.

Genetic mutation trade-offs lead to parallel evolution

EurekAlert! - Lun, 05/22/2017 - 22:00
Researchers at the University of Illinois at Urbana-Champaign have shown how evolutionary dynamics proceed when selection acts on two traits governed by a trade-off. The results move the life sciences a step closer to understanding the full complexity of evolution at the cellular level.

Recreational cocaine: Brain area involved in addiction activated earlier than thought

EurekAlert! - Lun, 05/22/2017 - 22:00
Even among non-dependent cocaine users, cues associated with consumption of the drug lead to dopamine release in an area of the brain thought to promote compulsive use, according to researchers at McGill University.

New chemical reaction developed at UCLA could eventually yield new fuels and medications

EurekAlert! - Lun, 05/22/2017 - 22:00
UCLA chemists have developed a new technique to convert carbon-hydrogen bonds into carbon-carbon bonds using catalysts made of silicon and boron, both abundant and inexpensive elements.

Using a genetic signature to overcome chemotherapy-resistant lung cancer

EurekAlert! - Lun, 05/22/2017 - 22:00
Patients with non-small cell lung cancer (NSCLC) often respond to standard chemotherapy, only to develop drug resistance later, and with fatal consequences. But what if doctors could identify those at greatest risk of relapse and provide a therapy to overcome or avoid it?

NASA sees powerful storms with advancing monsoon in Bay of Bengal

EurekAlert! - Lun, 05/22/2017 - 22:00
Storms associated with the advancing monsoon in the Northern Indian Ocean's Bay of Bengal were analyzed by NASA with the GPM or Global Precipitation Measurement mission core satellite.

The high plains aquifer: Can we make it last?

EurekAlert! - Lun, 05/22/2017 - 22:00
he heart of the United States is a highly productive agricultural region. This "breadbasket" underpins much of U.S. society, but it also relies almost entirely on a complex network of diminishing groundwater resources. In a short and provocative article, for GSA Today, Susan Stover and Rex Buchanan ask a simple question: "How long can the High Plains aquifer last?"
